Somehow I missed that in my skim through the docs.. d'oh.

This is only really "safe" if the end users never see the alternate
1..16 numbering.  (if folks have to operate simultaneously in 0-based
and 1-based numbering space, i can see unfortunate accidents because,
among other things, the system controller lets you power cycle

What I'm doing for now is to map 16 to 0, and 17 and 18 to
the switch consoles..
